Implements Tunnel type that listens on a local port, accepts WinBox client connections, dials the remote RouterOS device, and proxies traffic bidirectionally. Uses activityReader to atomically update LastActive on each read for idle timeout detection. Per-connection contexts derive from the tunnel context so Close() terminates all connections cleanly.
